In step 102, electronic equipment can before original image is projected, simultaneously or afterwards, indicating image collecting unit gathers image, the collection direction of image acquisition units is towards the perspective plane of projecting cell, when projecting to make projecting cell, image acquisition units can get the picture frame comprising projection image.Wherein, can be the IMAQ direction that user manually adjusts image acquisition units, also can be the collection direction that image acquisition units adjusts image acquisition units automatically.
In step 103, after electronic equipment obtains at least two two field pictures of image acquisition units collection, in each two field picture, feature object is determined according to image recognition technology, feature object wherein can for having the object of character shape, also can for having the object of signature identification (or mark), the object of default spatial relation can also be had, as being less than the object of setting threshold with the distance on perspective plane, etc.
In step 104, electronic equipment, by according to the spatial positional information of preset algorithm feature based object in each frame of at least two picture frames, determines the tracing point of a correspondence on the projection surface.Specifically, the spatial positional information of feature object can be the directional information of characteristic body body, a bit on feature object sensing perspective plane can be determined according to directional information, be tracing point, this characteristic locus can be that the projection image of original image is inner, also can outside the projection image of original image, the embodiment of the present invention will not limit.
When the relative perspective plane motion of feature object, the tracing point determined at least two picture frames is different, and connecting these tracing points can morphogenesis characters track.
In step 105, electronic equipment generates new projection strategy by conjunction with original image and projected footprint, forms the second projection image by projection unit projects, wherein, at the characteristic locus place indicating characteristic mark on perspective plane.
With reference to Fig. 4, at characteristic locus when the projection image of original image is inner, the second projection image is the characteristic locus place morphogenesis characters mark in projected image.

When obtaining a tracing point according to each picture frame, being coupled together by tracing point can morphogenesis characters track.In practical application, can be connected by straight line between the tracing point that adjacent image frame is corresponding, also can be connected by round and smooth curve.Such as, if the time interval of adjacent two frames of IMAQ is shorter, the close together of adjacent track point, can be connected by straight line.And if the time interval of adjacent two frames of IMAQ is longer, adjacent track point distant, is connected tracing point by curve, and the characteristic locus that can make is connected obtains is more natural, attractive in appearance.
Optionally, in the embodiment of the present invention, the spatial positional information of feature object comprises directional information and/or the positional information of feature object.Further, spatial positional information can also comprise the depth of view information of feature object.Such as, when pointing to the tracing point on perspective plane in conjunction with depth of view information and directional information determination feature object, the tracing point determined is more accurate.
Optionally, in the embodiment of the present invention, after step 104, can also comprise the steps:
Electronic equipment generates the operational order corresponding with characteristic locus according to preset algorithm;
Electronic equipment performs the operation corresponding with operational order.
Concrete, electronic equipment is after acquisition characteristic locus, the operational order corresponding with characteristic locus can be generated according to preset algorithm, if it is straight line left that spy detects track, instruction projecting cell can be generated and switch to the upper piece image be projected in before this original image of projection, such as, when showing PPT formatted file, projecting cell can be indicated to show a upper width lantern slide.When and for example projected footprint is circular, projecting cell can be indicated to terminate projection, etc., no longer to illustrate at this more.
By according to the instruction of characteristic locus generating run, and then realize the operation to electronic equipment, fast accurately.
Optionally, in the embodiment of the present invention, electronic equipment is at acquisition one characteristic locus, instruction projecting cell, according to after characteristic locus projection morphogenesis characters mark, will start timer, when timer expired, can no longer show this signature, exiting of realization character mark display.In actual conditions, while signature formerly, electronic equipment can obtain new characteristic locus, the signature that instruction projection unit projects makes new advances.
